Prelims

1. Which of the following best describes the 'fingerprinting' technique mentioned in the context of climate research?

   1. A A technique used to measure the exact volume of carbon sequestration in forest cover.
   2. B A statistical approach to distinguish natural climate variability from human-induced atmospheric changes.
   3. C A method to track the migration patterns of species affected by climate change.
   4. D A process of identifying the specific geographic origin of industrial aerosol pollutants.

2. According to the IIT-Delhi study, what is the primary role of aerosols in the context of the Indian monsoon?

   1. A They act as a primary driver for increasing the frequency of El Niño events.
   2. B They enhance the warming effect of greenhouse gases by trapping heat in the lower atmosphere.
   3. C They scatter sunlight and can suppress rainfall, partially masking the effects of greenhouse gas warming.
   4. D They are the main cause of the shift in the core monsoon zone toward the Himalayas.
